Default Ignition/Wiring Issues

I recently was able to restore power to my 1976 C3, but when I turn the key to the "on" position, the only 2 lights in the interior turn off and the starter does not engage. On top of this the brake lights are stuck on and I can't get them to turn off. Any help?

The instrument lights will not illuminate without a ground. I’m guessing the only two that ignite have two wires going to the bulb.

When you try to start it are you in park or neutral? If not the neutral safety switch will prevent the starting from working.

The brake light can be on either because of the emergency brake switch or the distribution block. The e brake switch is easy enough to get to in the center console, and you can try resetting the distribution block by quickly stomping the brake pedal. It may take several tries.

Suggest having a good wiring diagram & look where power & grounds should be, then test strategically to see if the expected components have the necessary good connections. It’s very difficult to give a direction when we don’t know the underlying details… is the wiring in engine bay & dash intact, ripped apart, what led to your current situation?

Battery power goes to to starter solenoid, ends with ground cables from frame in back & engine block… start there, work backwards, wiring in these cars aren’t terribly complicated, the diagram will be your ultimate guide… unless there’s all kinds of Bubba connections that complicate life.

That looks like a fun project to try to get running again. I like the challenge of getting old cars back on the road.

On my 1982 there is a brake light switch just above the pedal, I can’t see it in your pic but look for a white plunger like switch. If it’s not touch brake pedal arm it’s probably extending which lights up brake lights.

maybe buy a cheap push button remote starter switch, they are cheap….they are used to activate the starter without key, make sure your not under car, wheels are blocked and it’s in park if you use one. The remote switch is like hot wiring the car but a bit safer. The remote switch is to test if the starter is even working anymore. Make sure your battery is full above 12 volts and if starter sounds bound up sometimes you can tap the starter body with a small hammer to get it rolling again. Looks like it’s been sitting a while.
